Methods. Linear regression was used to relate log-measured GFR (mGFR) to sex, race, diabetes, transplant, weight, various transformations of creatinine and age with and without interactions. Equations were developed in a pooled database of 10 studies [2/3 (N = 5504) for development and 1/3 (N = 2750) for internal validation], and final model selection occurred in 16 additional studies [external va

I denna rapport redovisas en studie av kommunikationsmönster och strategier i konsultationer inom barndiabetesvården. En utgångspunkt för studien är att samtalsstrategier för att stödja upplevelsen av tilltro till sin förmåga att utföra vården av barnet kan urskiljas på mikronivå i samtalet. Fyra läkarkonsultationer inom barndiabetesvården har spelats in, transkriberats, analyserats och kompletter

Organometallic analogs of chloroquine (CQ) are of interest as drug candidates that may be able to overcome the widespread chloroquine resistance developed by malaria parasites. Two new chromium arene CQ-analogs: [η(6)-N-(7-chloroquinolin-4-yl)-N'-(2-dimethylamino-methylbenzyl)-ethane-1,2-diamine]tricarbonylchromium 4 and [η(6)-N-(7-chloroquinolin-4-yl)-N'-(2-dimethylaminobenzyl)-ethane-1,2-diamine

Tumor cell death potentially engages with the immune system. However, the efficacy of anti-tumor chemotherapy may be limited by tumor-driven immunosuppression, e.g., through CD25(+) regulatory T cells. We addressed this question in a mouse model of mesothelioma by depleting or reconstituting CD25(+) regulatory T cells in combination with two different chemotherapeutic drugs. We found that the effi

In aerial vehicle control design, the industrial baseline is to use robust control methods together with gain-scheduling to cover the full airspeed and altitude flight envelope. An adaptive controller could possibly add value by increasing performance while keeping robustness to deviation from nominal assumptions. In this thesis L1 adaptive control is studied and evaluated as it is applied to a pi

We show that condensation is an efficient particle growth mechanism that leads to growth beyond decimetre-sized pebbles close to an ice line in protoplanetary discs. As coagulation of dust particles is frustrated by bouncing and fragmentation, condensation could be a complementary, or even dominant, growth mode in the early stages of planet formation. Ice particles diffuse across the ice line and

In international research there is a near consensus that the importance of cities is growing. As the policymakers of contemporary cities redirect their policy orientations away from the goal of redistribution towards achieving economic competitiveness, and as they introduce new structures of governance, they are becoming more and more committed to entrepreneurial city politics. However, both the i

Following the work of Schwinger (1961 J. Math. Phys 2 407), we present a general method for deriving quantum response functions on a closed-loop contour in the complex time plane. We focus on optical response functions of linear to third order and demonstrate by projecting contour time onto the real axis how they connect to Liouville space pathways. This work highlights the close connection betwee

Objective We tested whether men and women in the European Society of Hypertension (ESH) high normal and normal blood pressure (BP) categories, all included in the the Seventh Joint National Committee (JNC 7) prehypertension group, share similar metabolic characteristics and whether they differ from men and women with optimal BP (

The atomic structure of calcium-silicate-hydrate (C-1.67-S-H-x) has been investigated by theoretical methods in order to establish a better insight into its structure. Three models for C-S-H all derived from tobermorite are proposed and a large number of structures were created within each model by making a random distribution of silica oligomers of different size within each structure. These stru

To gain entry into target cells, HIV-1 binds to CD4 via the viral glycoprotein gp120. This interac-tion initiates a series of events including binding of a coreceptor, CCR5 and/or CXCR4, and ulti-mately leads to gp41-mediated fusion of the viral and cell membranes. CCR5-restricted (R5) vi-ruses predominate in early, asymptomatic stages of the infection. Emergence of viruses able to use CXCR4 inste

A polygonal finite-element formulation is applied to solve electromechanically coupled inhomogeneous boundary value problems for polycrystalline materials. Each grain is discretised by one single polygonal finite element, which allows the efficient simulation of general boundary value problems which still resolves individual grains in space. The constitutive model proposed for switching in piezoce

Background: Risk factors for hip fracture are well studied because of the negative impact on patients and the community, with mortality in the first year being almost 30% in the elderly. Age, gender and fall risk-increasing drugs, identified by the National Board of Health and Welfare in Sweden, are well known risk factors for hip fracture, but how multimorbidity level affects the risk of hip frac

De intresseområden som representerades vid forskningssymposiet kan ses på en skala med fokus som varierar mellan mikro- och makroperspektiv: Från fokus på den enskilde tonsättarens, körledarens eller körsångarens musikaliska uttryck till fokus på frågor om körsångens betydelse ur ett större samhälleligt och internationellt perspektiv.

The position generator is a widespread method for measuring latent social capital in which respondents are queried about contacts on a list of occupations predefined by the analyst. We separate out the unique contribution of each occupation to aggregated measures of social capital. It turns out that this contribution varies vastly: knowing a person in some occupations provides substance to measure

Popular Abstract in Swedish Till processindustrin räknar man bland annat fabriker som tillverkar papper, plast och livsmedel. I en enda fabrik kan det finnas tusentals PID-regulatorer som har till uppgift att styra storheter som tryck, flöden och temperaturer till önskade värden. PID-regulatorns roll i processindustrin har därför jämförts med den arbetsmyran har i myrstacken. Huruvida en enskild mA large process industry can have somewhere between five hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single controller. This thesis presents tools for analys
